I am trying to run a python script to generate heatmap and clustering dendrogram. But I got an error message saying :

import: unable to open X server @ error/import.c/ImportImageCommand/361

I am a new to both linux and python. So I cannot make out utterly why the error happened. Dose anyone know how to solve this problem?

My OS is linux fedora.

Thanks.

  • Can you tell a little bit more ? Python version, which part of your code generates that error ? etc...

Your script is being interpreted by a shell instead of python. The shell attempts to execute the X import command and that external /usr/bin/export command prints the error.

Make sure you have

#!/usr/bin/env python

at the top of each python executable script (not necessary for imported libraries). This causes the script to be interpreted by python.
